Globally, food systems are the most significant cause of environmental change; therefore, efforts to create more environmentally sustainable food systems are presented. One of the directions is strengthening the local actors and short food supply chains. Simultaneously, changes in farming systems are needed, and organic agriculture is one of the ways to make food systems more environmentally sustainable. Despite the abundance of research on the environmental consciousness of consumers in short food supply chains, the question is raised whether local food chain farmers are also committed to environmental sustainability. Therefore, this paper aims to explore the importance of environmental sustainability to organic short food supply chain actors. More specifically, the research depicts the views of organic farmers and consumers and their relation to the actual environmental sustainability of short food supply chains. During the research, a specific short food supply chain – a direct purchasing network – was explored. A qualitative approach was applied to reach the aim. Thus, in-depth interviews and observations were used as a research method. The research results demonstrated the views of farmers and consumers of the specific network regarding environmental sustainability aspects in the network. In the research, such environmental aspects as the circularity of resources, biodiversity, chemicals in the environment, seasonality and locality of diets, and the distance (food miles) were admitted as crucial ones by the specific short food supply chain actors. The differences in opinions of consumers and farmers emerged when thinking about the scale of their views.

This study describes dynamics in hydrology, morphometry, and water mass movement in Lake Kisezers. The analysis of Lake Kisezers’ morphometry dynamics according to the rapidly changing environment has been carried out. The determination of dynamics in morphometry comes before understanding potential exploitation and environmental sustainability of water body. Lake Kisezers is situated in a densely populated area. Without understanding and deciphering all possible environmental factors influencing Lake Kisezers, the water body can degrade and become of poor environmental quality. Such changes can lead to irreversible changes in the lake ecosystem and degradation of the surrounding landscape. This study aims to identify and explain the elements that influence Lake Kisezers’ hydrological regime, catchment area, and bathymetry. Lake Kisezers is hardly influenced body of water with rapid hydrological and morphometric dynamics. The research is possible due to extensive data availability and the importance of the water body location. Lake Kisezers affects the city of Riga and its surrounding area with a danger of flooding and decreasing land exploration potential. This study results in better understanding in the factors influencing hydrology and morphometry in Lake Kisezers and possible environmental sustainability endangerment in the future. The main impact factor is the connectivity to the River Daugava and its unique hydrological regime. For Lake Kisezers, environmental balance is necessary to continue research and develop a hydrological change model. This study was conducted with fieldwork data and open-source cartographic, geospatial, water level, and mass movement data. The research seeks to understand what is necessary to maintain environmental sustainability in Lake Kisezers.
